DETAILED DESCRIPTION OF THE INVENTION

The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some of the embodiments of the present invention rather than all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present disclosure.

As shown in FIG. 1, the present invention provides a paired air pressure energy production system, which comprises a paired air pressure energy storage device 1, a pneumatic compressor 2 and a power device 3. The paired air pressure energy storage device includes a high pressure air container 11 and a low pressure air container 12, the high pressure air container 11 is filled with first gas, and the low pressure air container 12 is filled with second gas. The pneumatic compressor 2 is connected with the low pressure air container 12 and the high pressure air container 12 respectively. The pneumatic compressor 2 is used for transferring the second gas in the low pressure air container 12 into the high pressure air container 11. Air pressure difference is formed between the high pressure air container 11 and the low pressure air container 12 and the air pressure difference is the paired air pressure energy, that is, air pressure difference capable of reflecting paired air pressure energy is formed between the high pressure air container 11 and the low pressure air container 12. The paired air pressure energy is formed in the paired air pressure energy storage device 1 and the power device 3 is connected with a rotating shaft 21 of the pneumatic compressor 2 for driving the rotating shaft 21 of the pneumatic compressor 2 to rotate.

Specifically, in a feasible embodiment, the high pressure air container 11 includes at least one sealed cylinder filled with high pressure gas, and the low pressure air container 12 includes at least one sealed cylinder filled with low pressure gas.

In another feasible embodiment, as shown in FIG. 2, the paired air pressure energy storage device 1 includes an inner body 13 and an outer body 14 sleeved on the outside of the inner body 13. The inner body 13 is filled with first gas, a chamber 15 formed between the outer body 14 and the inner body 13 is filled with second gas. In the present embodiment, the inner body 13 is the high pressure air container 11, and the chamber 15 is the low pressure air container 12; or, in other embodiments, the inner body 13 is the low pressure air container 12 with second gas filled therein, and the chamber 15 is the high pressure air container 11 with first gas filled therein. When the paired air pressure energy storage device 1 is located on the ground, at the moment, the inner body 13 is the high pressure air container 11, the first gas therein is high pressure gas, the chamber 15 is the low pressure air container 12, and the second gas therein is low pressure gas. When the paired air pressure energy storage device 1 is located underwater or underground, because underwater or underground pressure environment is high pressure, at the moment, the inner body 13 is the low pressure air container 12, the second gas therein is the low pressure gas, the chamber 15 is the high pressure air container 11, and the first gas therein is high pressure gas, and thus being favorable for alleviating stress on the wall of the outer body 14 and offsetting the retracting pressure of the outer body 14.

In the present embodiment, the intensity of pressure of the high pressure gas is higher than that of the low pressure gas, that is, the intensity of pressure of the first gas is higher than that of the second gas. The intensity of pressure of the first gas may be 0.1 MPa-100 MPa, and the intensity of pressure of the second gas may be 100 Pa-30 MPa. Further, the first gas and the second gas may be selected from air, or nitrogen, or helium, or mixture of other gases; and the mixture of the other gases, for example, may be a mixture of nitrogen and helium, etc.

In the embodiment of the present invention, a compressor known in the prior art may be adopted as the pneumatic compressor 2, and an aim of transferring the second gas in the low pressure air container 12 into the high pressure air container 11 is achieved by the compressor, while the specific structure and working principle of the compressor will not be further described herein. The pneumatic compressor 2 may realize an effect of storing mechanical energy in the paired air pressure energy storage device 1 in the form of paired air pressure energy.

In an optional embodiment of the power device 3, the power device 3 may be a wind turbine 31, and the wind turbine 31 is connected with the rotating shaft 21 of the pneumatic compressor 2. The wind turbine 31 is used for driving the rotating shaft 21 of the pneumatic compressor 2 to rotate, so as to start the pneumatic cylinder 2 to work, and thus achieving the aim of transferring the second gas in the low pressure air container 12 into the high pressure air container 11. The wind turbine 31 may collect wind energy in natural environment, for example, wind power on the land, on the water surface or in the air, and convert the wind energy into mechanical energy to be acted to the rotating shaft 21 of the pneumatic compressor 2.

As shown in FIG. 3, the wind turbine 31 comprises a horizontal wind tower 311, a first wind wheel 312 and a second wind wheel 313 are respectively provided at two sides of the horizontal wind tower 311. The first wind wheel 312 is in an upwind position with respect to the second wind wheel. The paired air pressure energy storage device 1 is provided at the lower end of the horizontal wind tower 311, the pneumatic compressor 2 is located between the horizontal wind tower 311 and the paired air pressure energy storage device 1, and the first wind wheel 312 and the second wind wheel 313 are respectively in driven connection with the rotating shaft 21 of the pneumatic compressor 2. By fixing the horizontal wind tower 311 on land, or placing the horizontal wind tower 311 on a floating object floating on the water surface, or fixing support pillars on land, the horizontal wind tower 311 is connected above the support pillars, so that the horizontal wind tower 311 is located in the air above the land, and the aim of collecting wind energy in natural environment is achieved by using the first wind wheel 312 and the second wind wheel 313. Communication electronics, power electronics and motor facilities do not need to be provided in the horizontal wind tower 311, and therefore, the construction cost of the horizontal wind tower 311 is low, the maintenance cost is more cost-effective, and system equipment is more durable. In addition, the horizontal wind tower 311 is actually of a hollow structure, the paired air pressure energy storage device 1 and the pneumatic compressor 2 are both located in a cylinder chamber at the lower end of the horizontal wind tower 311, and the hollow structure is capable of enabling the horizontal wind tower 311 to be located on a shaking plane, and thus being especially suitable for collecting wind energy in water floating type, deep sea and low-speed moving places and in the air. Furthermore, due to the inherent hollow buoyancy characteristic of the horizontal wind tower 311, the horizontal wind tower 311 does not need to be fixedly supported on the underwater ground, and therefore, the underwater engineering construction cost, environment protection cost and operation and maintenance cost of the horizontal wind tower 311 are remarkably lowered, and influence to underwater environment is reduced.

In the implementation manner of the present invention, a distance between the second wind wheel 313 and the horizontal wind tower 311 is greater than a distance between the first wind wheel 312 and the horizontal wind tower 311. Such setting has the advantage that the wind aligning torque force of the second wind wheel 313 is stronger than that of the first wind wheel 312, so that the horizontal wind tower 311 acquires a capability of automatically aligning to wind or yawing. The wind aligning torque force is wind power born by the second wind wheel 313 or the first wind wheel 312 multiplied by a distance from respective wind wheels to the horizontal wind tower 311.

In the implementation manner of the present invention, the first wind wheel 312 and the second wind wheel 313 both comprise a plurality of vanes 314. Specifically, as shown in FIG. 4, in a feasible embodiment, the first wind wheel 312 and the second wind wheel 313 respectively includes two vanes 314, and the two vanes 314 are oppositely and radially arranged along the rotating center 315 (that is, the aftermentioned first wind wheel rotating shaft 3121 or second wind wheel rotating shaft 3131). Of course, in another feasible embodiment, as shown in FIG. 5, the first wind wheel 312 and the second wind wheel 313 also may respectively include three vanes 314, and the three vanes 314 are arranged at equal intervals along the peripheral direction of the rotating center 315; or in other embodiments, the first wind wheel 312 and the second wind wheel 313 may also respectively comprise four vanes 314 or more vanes 314, which is not limited herein.

In the implementation manner of the present invention, in a feasible embodiment, each vane 314 comprises a plurality of sub-vanes which are sequentially connected from inside to outside. The plurality of sub-vanes are connected to a vane shaft 3147, the vane shaft 3147 is used for connecting the vanes 314 to the aftermentioned first wind wheel rotating shaft 3121 or second wind wheel rotating shaft 3131, and the vanes 314 are designed to be of a segmented structure, thus saving the manufacture, transportation and maintenance cost of the vanes; and in another feasible embodiment, the vanes 314 may also be integrally formed on the vane shaft 3147, which is not limited here.

Specifically, in a design scheme that the vanes adopt a segmented structure, a first sub-vane 3141, a second sub-vane 3142 and a third sub-vane 3143 are sequentially connected from the inner edge of the vane 314 to the outer edge of the vane 314; of course, in other embodiments, the quantity of the sub-vanes on each vane 314 may also be selected and set according to actual requirements, for example, each vane 314 comprises two sub-vanes, or four sub-vanes, or more sub-vanes, which is not limited here.

Further, please refer to FIG. 4, the length of the third sub-vane 3143 at the outer edge of the vane 314 is greater than that of the second sub-vane 3142 and the length of the first sub-blade 3141 at the inner edge of the vane 314; and the thickness of the third sub-vane 3143 at the outer edge of the vane 314 is smaller than the thickness of the second sub-vane 3142 and the first sub-blade 3141 at the inner edge of the vane 314. Such design has the advantages that on one hand, vane segmentation is favorable for segmented maintenance according to requirement, instead of overall maintenance; and on the other hand, vanes 314 of different sizes are adopted as the segmented vanes, which is favorable for the overall mechanical loading of the vane 314, that is, when the load of a blade is constant, the overall length of the vane 314 may be extended by thinning and narrowing the third sub-vane 3143 at the outer edge of the vane 314, so as to obtain a larger swept area.

Specifically, taking a condition that each vane 314 comprises three sub-vanes an example, the length of the sub-vane at the outer edge of the vane 314 is the length L3 of the third sub-vane 3143, the length of the sub-vane at the inner edge of the vane 314 is the length L1 of the first sub-vane, that is the length L3 is greater than the length L1; in addition, the thickness of the sub-vane at the outer edge of the vane 314 is the thickness H3 of the third sub-vane 3143, the thickness of the sub-vane at the inner edge of the vane 314 is the thickness H1 of the first sub-vane 3141, that is, the thickness H3 is smaller than the thickness H1. In the embodiment as shown in FIG. 4, the length L3 of the third sub-vane 3143 is greater than the length L2 of the second sub-vane 3142, and the length L2 of the second sub-vane 3142 is greater than the length L1 of the first sub-vane 3141; the thickness H3 of the third sub-vane 3143 is smaller than the thickness H2 of the second sub-vane 3142, and the thickness H2 of the second sub-vane 3142 is smaller than the thickness H1 of the first sub-vane 3141. In a feasible embodiment, the total length (that is the sum of the length L1, the length L2 and the length L3) of the vane 314 is 0.3 m-50 m.

In the implementation manner of the present invention, as shown in FIG. 3, the first wind wheel 312 is in driven connection with the rotating shaft 21 of the pneumatic compressor 2 by the first wind wheel rotating shaft 3121, the second wind wheel 313 is in driven connection with the rotating shaft 21 of the pneumatic compressor 2 by the second wind wheel rotating shaft 3131, a plurality of vanes 314 of the first wind wheel 312 are connected to the first wind wheel rotating shaft 3121, and a plurality of vanes 314 of the second wind wheel 313 are connected to the second wind wheel rotating shaft 3131.

Specifically, a bevel gear 211 is connected to the rotating shaft 21 of the pneumatic compressor 2, the bevel gear 211 is located in the horizontal wind tower 311, an upper first wind wheel bevel gear 3122 is connected to one end, stretching into the horizontal wind tower 311, of the first wind wheel rotating shaft 3121, a plurality of vanes 314 of the first wind wheel 312 are connected to the other end of the first wind wheel rotating shaft 3121 by respective vane shafts 3147, a lower second wind wheel bevel gear 3132 is connected to one end, stretching into the horizontal wind tower 311, of the second wind wheel rotating shaft 3131, a plurality of vanes 314 of the second wind wheel 313 are connected to the other end of the second wind wheel rotating shaft 3131 by respective vane shafts 3147, and the upper first wind wheel bevel gear 3122 and the lower second wind wheel bevel gear 3132 are respectively in driving connection with the bevel gear 211. Under the action of wind energy in the natural environment, a plurality of vanes 314 of the first wind wheel 312 and a plurality of vanes 314 of the second wind wheel 313 rotate to drive the first wind wheel rotating shaft 3121 and the lower second wind wheel bevel gear 3132 to rotate, so that the bevel gear 211 connected to the rotating shaft 21 of the pneumatic compressor 2 rotates under the combined action of the first wind wheel bevel gear 3122 wind wheel rotating shaft 3121 and the lower second wind wheel bevel gear 3132, and the aim of driving the rotating shaft 21 of the pneumatic compressor 2 to rotate is achieved.

According to the present invention, in order to make the bevel gear 211 rotate toward one direction, the rotating directions of the first wind wheel bevel gear 3122 wind wheel rotating shaft 3121 and the lower second wind wheel bevel gear 3132 are opposite, that is, the rotating direction of the plurality of vanes 314 on the first wind wheel 312 is opposite to the rotating direction of the plurality of vanes 314 on the second wind wheel 313, and the first wind wheel 312 and the second wind wheel 313 are in a counter rotating state. Such design has the following advantages: on one hand, the aim of making the rotating shaft 21 of the pneumatic compressor 2 rotate toward one direction is achieved; and on the other hand, when the wind turbine 31 is under the action of wind power, the first wind wheel 312 and the second wind wheel 313 with opposite rotating directions may generate counter rotating torque relative to the horizontal wind tower 311, such counter rotating torque is favorable for promoting the synthesis torque of the first wind wheel rotating shaft 3121 and the lower second wind wheel bevel gear rotating shaft 31321, and therefore, a symmetric acting force of the first wind wheel 312 and the second wind wheel 313 to the horizontal wind tower 311 is eliminated, not only may wind energy utilization rate of the wind turbine 31 in unit swept area be increased, but also wind energy collection efficiency is increased; meanwhile, horizontal counter rotating torques generated by the first wind wheel 312 and the second wind wheel 313 respectively are synthesized to be a single vertically downward torque at the top of the horizontal wind tower 311, so as to promote the start of the pneumatic compressor 2, and thus being favorable for converting wind energy into mechanical energy.

In the implementation manner of the present invention, observing from the left side or the right side of FIG. 3, a plurality of vanes 314 of the first wind wheel 312 and a plurality of vanes 314 of the second wind wheel 313 are arranged in a staggered way along the peripheral direction of the first wind wheel rotating shaft 3121 and the peripheral direction of the lower second wind wheel bevel gear rotating shaft 31321. In the present embodiment, FIG. 6 is a view of the FIG. 3 observing from the left side, when the first wind wheel 312 comprises two vanes 314, and the second wind wheel 313 also comprises two vanes 314, the two vanes 314 of the first wind wheel 312 are respectively arranged by staggering from the two vanes 314 of the second wind wheel 313, that is, the vanes are arranged in an orthogonal way by forming an angle of 90 degrees. Such setting has the advantage that wind aligning area shielding of the first wind wheel 312 is minimum relative to the second wind wheel 313.

In the implementation manner of the present invention, as shown in FIG. 7, in an embodiment that each vane 314 is formed by splicing a plurality of sub-vanes, each sub-vane in each vane 314 is formed by two rotatably connected vanes 3144 and a blade angle vane 3145, wherein two blade angle vanes 3145 of two adjacent sub-vanes of each vane 314 are connected with each other by a first connecting member 3146, and the vanes 3144 of each sub-vane of each vane 314 is connected to respective vane shaft 3147. Each sub-vane is segmented into two vanes 3144 with a certain connection relation mutually and a blade angle vane 3145, so as to be convenient for locally adjusting the angle of individual sub-vanes in field according to the wind regime of a wind field, and in maintenance, the vanes 3144 and/or the blade angle vane 3145 of individual sub-vanes may be locally replaced, instead of replacing the whole vane of the wind wheel.

Specifically, taking a condition that each vane 314 in the present invention comprises three sub-vanes (the first sub-vane 3141, the second sub-vane 3142 and the third sub-vane 3143) as an example, in the present embodiment, the shape of cross section of each sub-vane of each vane 314 is approximately approximately an obtuse triangle, and by making a vertical line towards the bottom edge by taking the obtuse angle of the obtuse triangle as a top point, vane bodies located at two sides of the vertical line are the vanes 3144 and the blade angle vane 3145, and the vanes 3144 and the blade angle vane 3145 are designed to be of mutually rotatable structures at the top point of the obtuse angle of the obtuse triangle, for example, the vanes 3144 and the blade angle vane 3145 may be mutually rotatably connected by a hinge; further, elastic members 3148 are connected between the vanes 3144 and the blade angle vanes 3145, in the present embodiment, the elastic members 3148 are springs, the elastic members 3148 are located at the bottom edge of the obtuse triangle and used for elastically connecting the vanes 3144 and the blade angle vanes 3145, and in a specific embodiment, the blade angle vanes 3145 can rotate by 0°-30° relative to the vanes 3144.

Please refer to which are shown in FIG. 7 and FIG. 8 in match, along a direction from the inner edge to the outer edge of each vane 314, the area of the cross section of each sub-vane in each vane 314 is gradually reduced, for example, in the present embodiment, the area of the cross section of the first sub-vane 3141 is greater than the area of the cross section of the second sub-vane 3142, and the area of the cross section of the second sub-vane 3142 is greater than the area of the cross section of the third sub-vane 3143. Such setting has the advantages that a production process with equal uniform section is adopted for each sub-vane, and therefore, the manufacture, transportation and maintenance cost of the vanes is saved, and lift vane forming may be distinguished from exiting vane forming.

Further, in the implementation manner of the present invention, in a feasible embodiment, the first wind wheel 312 and the second wind wheel 313 respectively comprise a plurality of adjusting blades 316, one adjusting blade 316 is provided between every two adjacent vanes 314 of the first wind wheel 312 and also between every two adjacent vanes 314 of the second wind wheel 313, and a linkage member 317 is connected between each of the adjusting blades 316 and one vane 314 adjacent to the adjusting blade 316. These adjusting blades 316 may receive and sense wind power acting on the horizontal wind tower 311, and transfer this acting force to the blade angle vane 3145 of each vane 314 by the linkage members 317.

Specifically, each adjusting blade 316 is rotatably connected to the vane shaft 3147. This adjusting blade 316 is connected to the blade angle vane 3145 of each the first sub-vane 3141 at the inner edge of the vane 314 by the linkage member 317. As shown in FIG. 7 and FIG. 8, when the wind power is increased or rotating speed is raised, wind power received by the face of the adjusting blade 316 is increased accordingly, offset of the adjusting blade 316 along the wind power direction is increased, and the angle of the vane 314 is adjusted by utilizing the offset acting force. In order to achieve this arm, firstly, the adjusting blade 316 transfers the received wind power to the connected blade angle vane 3145 by the linkage member 317, so that the blade angle vane 3145 is stressed, and the blade angle vane 3145 rotates by a certain angle around the vane 3144, so as to realize linkage adjustment of the blade angle of the vane 314. According to the present invention, under the action of wind power of the natural environment, the blade angle vanes 3145 of a plurality of vanes 314 are driven to rotate by a plurality of adjusting blades 316, so as to automatically adjust the rotating speed of a plurality of vanes 314 on the first wind wheel 312 and a plurality of vanes 314 on the second wind wheel 313 around the first wind wheel rotating shaft 3121 and the second wind wheel rotating shaft 3131, and therefore, the self-start capacity at low wind speed and the autonomous sheltering capacity at a strong wind speed of the wind turbine 31 are promoted.

By virtue of these floating mechanisms 321, the paired air pressure energy production system may be provided on water or on the sea, and energy generated by up and down surging of water waves is received and transferred by a plurality of floating components 3212.
